| Description |
There are large numbers of structures being collapsed every year under normal loads whose life may be in the range of 10-50 years. There may be stray incidents of newly built structures being collapsed. In view of this it is necessary to assess the health of the structures regularly and rehabilitate and retrofit if necessary. If the retrofitting is performed to make the structures safe for earthquake loads, it can encompass the requirement of normal loads also. In the present talk, brief introduction to the earthquake design of structures including supporting equipment of nuclear facilities will be provided. Focus is given to the procedure and methods of retrofitting of existing structures and equipment. Also briefly discussed the research carried out to develop new methods of retrofitting including numerical analysis and experimental aspects.
